The ADG1221/ADG1222/ADG1223 are low-static-current, low-leakage iCMOS dual SPST switches with a ±15V/+12V supply range, 3V logic-compatible inputs, a switch resistance of 120Ω, a switch capacitance of 2pF, a switch leakage of 20pA, and a 10-lead MSOP package.
The ADG1221, ADG1222, and ADG1223 are iCMOS dual SPST switches offering low charge injection (<0.5 pC) and low off‑capacitance (2 pF). They operate from a ±15 V or +12 V supply and feature 3‑lead MSOP packaging.
The document provides detailed specifications, pin configurations, functional block diagrams, and ordering information for designers of test equipment, data‑acquisition, and signal‑routing applications.
